Strange thing. Have you checked that they are totally UV-erased before writing?I just checked the EPROMs that I had flashed, they are not good. There is only 16KB of writing on the 32KB of the file.
Nice work!
Maybe, it was done via BIOSUTIL.
Finally after verification, it is I who reversed even and odd on the labels of my Eprom. I have difficulties with this notion.
Yes, I also think so but then my CPU should work overclocked, i.e. at 12MHz, not 8MHz.I do not think that replacing the CPU will change anything. At that time, unlike today, the CPU speed is not detected by the motherboard. It is the division of the oscillator that defines the frequency, either without possibility of change, or with jumpers / switches or by software like SPEED (or the BIOS) in our case.
Nice) Then BIOSUTIL works correctly and my BIOS functions well.Finally after verification, it is I who reversed even and odd on the labels of my Eprom.
Some news today. Unfortunately the contact for the documentation has not yet found it. It still has cardboard to explore but in the end it is not sure to have it yet ... To be continued.
Good news, at least he hasn't forgotten about it. I hope he finds that finally(...)
